ATTORNEYS Patented Aug. 1e, 1932 UNITED STATES PATENT OFFICE' JOHANN JACOB KEYSER, OF AARAU, SWITZERLAND SPINDLE RAIL Application filed October 16, 1929, Ser-iai No. 400,011', and in Germany and SwitzerlandrN'ovember 5, 1928.

I have tiled applications for Letters Patent in Switzerland and Germany on Nov. 5, 1928.

This invention relates to a spindle rail for speed Y frames, spinning frames, doubling frames, etc., having the .spindles arranged in staggered relation to each other.

In the known spindle rail, in which the spindles are arranged in two rows and the driving shaft disposed between these, there y is an appreciable disadvantage consisting in the fact that the two rows rotate in opposition to each other, thus causing a very strong aXi al thrust to be exerted on the driving shaft.

It is the object of the present invention to overcome this drawback, and this is accomplished by the fact that the pitch of the heli- Y cal gears for operating the oppositely disposed rows of spindles is directed alternately to the left and the right with a view to attaining rotation of the two rows of spindles` in the one direction and thus avoiding axial thrust on the main driving vshaftthat is to say, the helical gears are furnished alternately with left and right vhand pitch.V

To facilitate the mounting of the driving shaft and the helical gears for the spindles and the bobbins the spindle rail is divided horizontally, while the bottom and top portions thereof serve as a means ofV mountingA and housing the helical gears. y

The invention will now be described more fully with reference to they accompanying drawing, in which Fig. 1 is a view in part section of a spindle rail for a speed frame (flyer).

Fig. 2 is the plan view, partly in section, of an opened spindle rail.

The spindlerail consists of the lower portion l, which is divided longitudinally into a plurality of sections, a similarly divided cover portion 2, and screws 3 holding the two parts together. The tight connection between the upper and lowerportions l and 2 is obtained by means of packing material inserted in grooves 4. The single sections of the lower portion l are held together by means of screws 5. Y

In the lower portion 1, secured by means of nuts 6, are bushes 7, on which run worm sleeves 8, which protrude upwardly through the cover portion 2, are secured against displacement bymeans of an abutment 9, andv serve to drive the bobbins 16. Between the two rows of spindles, running in ball or roller bearings l0, isthe driving shaft 11.

Firmly mounted on the driving shaft ll are muft's l2, and on these are located the i helicalgears 18 and 14, which are driven by friction or by means of friction couplings. The helical gears 13 and 14 are4 furnished alternately with left and right hand pitches,"

so that the axial thrust is mutually balanced.

jeo

Due vto the relatively disposed pitches the It will be understood that no restriction is made to the specific forni of embodiment as shown, and that various modifications may be made within the meaning of the abovea-nd the appended claim without departing from the spirit of the invention.

What I claim as new and desire to secure by Letters Patent is:

vIn a spindle rail for speed frames, spinning frames, `doubling frames and the like, a. casing divided through its medial longitudinal plane, providing upper and lowerv sections, said sections having complemental bearing members, a drive shaft journalled in said bearing members, said drive shaft having gears thereon, a plurality of spindles mounted 'in said lower section and each having a worm gear in mesh with a respective gear `on said drive shaft', said worm gears having an abutment upon their upper ends for engagement kinds of spinning by said upper section, and means for securing said upper section to said lower section whereby to retain the parts in operative relation.

In testimony signature.
